Stipulations and the Choice to Dissolve a Business Deal

13. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from al-Washsha’ from ‘Abd Allah ibn Sinan who has said the following: “Abu ‘Abd Allah عليه السلام, has said, ‘Abu ‘Abd Allah عليه السلام, has said, ‘In the case of slaves the deal becomes binding after three days. If slaves may have certain defects such as mental condition, leprosy and so on. It becomes binding after one year if the defect is insanity. After one year the choice does not remain of any effect.’”
